What allows different classes derived from the same base to respond differently to the same function call?

Function overloading
Virtual functions
Templates
Function pointers

The correct answer is: Virtual functions

Virtual functions allow different classes derived from the same base to respond to the same function call in different ways. This is because virtual functions are defined and implemented in the base class, but can be overridden in the derived classes, allowing them to have their own unique implementation of the function. This is known as polymorphism, which allows for more dynamic and versatile code. Function overloading (A) is a different concept where multiple functions can have the same name but different parameters. This does not allow for different responses from classes. Templates (C) are used for generic programming and do not directly impact the way classes respond to function calls. Function pointers (D) are simply pointers to functions and do not have any impact on how classes respond to function calls.
